Field notes
The homepage describes a package-name-based setup: customers identify apps to watch, while Rival Delta says it handles installs and runs each release as a new user. Its listed comparison scope extends from onboarding screens and paywalls to embedded SDKs and permissions. The sample digest names real app brands, but the page cautions that its displayed change lines are illustrative rather than confirmed findings.
